文章分析了转台式三轴天线工作原理,对方位与第三轴在系统跟踪时产生的轴间耦合扰动力矩进行推导,提出了采用前馈补偿方式来降低轴间耦合扰动对系统跟踪的影响,最后采用SIMULINK仿真软件对前馈补偿设计建模仿真,最终利用仿真结果验证了前馈补偿设计对抑制转台式三轴天线轴间耦合扰动是非常有效的。
- Abstract:
- In this paper,based on the analyse of the working theory of three axes antenna and the diagnostics of coupling torque produced by AZ and the 3rd axis. A feedforward compensation method is proposed to reduce the affection of the coupling disturbance on system tracking. Simulink is used to simulate and modeling in feedforward compensation design, The result proves the method is effective to eliminate the coupling disturbance of three axes antenna.
